How to Operate the Chiller Correctly?

After purchasing industrial chiller equipment, users should pay attention to the installation precautions of the equipment, which will greatly improve the performance of the industrial chiller. First of all, before installing the industrial chiller, the machine should be fully inspected to see if it is in good condition. Whether the installation place is open and the location is appropriate. Appropriate and sufficient space should be selected for the normal operation of the industrial chiller and future maintenance. It is recommended to use cement hard ground and install installation pads on the installation ground. The thickness of the installed ground cement is about 50mm, and it can bear the running weight of the industrial chiller.

The temperature of the room where the industrial chiller is installed should be between 5°C and 35°C. There are no obstructions around and above the industrial chiller, and enough space is reserved for smooth ventilation to ensure the normal operation of the industrial chiller. The pipeline installation space of the industrial chiller should also be abundant, and the pipeline connection part can be used for door openings or other suitable openings. The water in the room should be unobstructed. The water pipe of the industrial chiller should choose the appropriate pipe diameter to ensure the flow and pressure of the cooling system and the chilled water system when the industrial chiller is running at the maximum power, and to ensure that the pipe fittings are correctly connected to each other.

The rational use of the efficiency of industrial chillers is the main method to improve the efficiency of industrial chillers. When using the industrial chiller, reasonably select the capacity of the cold water, or adjust the operating speed of the industrial chiller. The load experiment shows that the industrial chiller is between 70% and 80% under the condition of ensuring the safe operation of the refrigeration equipment. When the load is running, the power consumption per unit of cooling capacity is the smallest.

Reducing the condensing temperature of industrial chillers is an important way to improve the refrigeration performance of industrial chillers. On the premise of meeting the operation and installation of industrial chillers and meeting the cooling demand, try to increase the evaporating temperature and reduce the condensing temperature. For example, when installing a water-cooled industrial chiller, there should be a certain margin when choosing a matching industrial cooling tower. At the same time, the operation of the pipeline water pump and the cooling tower should be comprehensively considered, and the original cooling tower circulating water system should be increased. Retrofit to ensure the cooling efficiency of the cooling water.

Avoiding and reducing pipe fouling in industrial chillers can improve the heat exchange efficiency of condensers and evaporators. When the industrial chiller runs for a long time, if the cooling water and chilled water in the system are not disposed of properly, calcium bicarbonate and magnesium bicarbonate in the circulating water will produce calcium carbonate and magnesium carbonate, which will accumulate on the pipe wall of the pipe or heat exchanger. On the other hand, the thermal conductivity is lowered, the heat exchange efficiency of the condenser and the evaporator is affected, and the power consumption of the equipment is increased. Therefore, when we use industrial chillers, we should use corresponding technologies to technically treat water, and regularly descale and clean water system pipes and cooling towers to improve heat exchange efficiency.
